肯定句变为否定句的方法;一般疑问句的回答
1)肯定句变为否定句的方法
把肯定句改成否定句分以下情况:
1、
句中有be动词的,在be动词后加not;
2、
句中有情态动词的(can
,should,must
,would),在情态动词后面加not;
3、
句中没有be动词和情态动词的,在动词前加don’t或doesn’t
;
①
句中动词为原形的,加don’t
.如:
I
like
apples.
——>I
don’t
like
apples.
②
句中动词为三单形式的,加doesn’t,并将三单式的动词还原成原形。
如:He
likes
apples.——>
He
doesn’t
like
apples.
4.肯定句中的some在否定句中应改为any。如:There
are
some
students
in
the
classroom.
——>
There
are
not
any
students
in
the
classroom.
